To be annoyed or unhappy. Primarily heard in US. The outcome of that race left me grumbling in the gizzard—I thought for sure I had bet on the right horse!
grumble about (someone or something)
To complain or gripe about someone or something. I turned the thermostat up, so you all can stop grumbling about how cold it is in here, thanks. Of course Marjorie is grumbling about how I left dishes out in the kitchen—she's not happy unless everything is perfectly put away.
grumble at (someone)
To complain or gripe to someone about someone or something. I turned the thermostat up, so you all can stop grumbling at me about how cold it is in here, thanks. Of course Marjorie is grumbling at anyone who will listen about how I left dishes out in the kitchen—she's not happy unless everything is perfectly put away.
